as soon as it appears in temp foulder, it start creating useless files language.bin and reproducing foulders. It fills the disk at great speed. If you try to delete it, you can't. Unlocker does not work on it. When Windows is started in safe mode, the file cannot be seen nor found.
This is the Bluetooth interface for the Acer TravelMate laptop, and derivatives.

This is the main program for RealTek HD Audio driver (Audio Rerouter). It is essential to RealTek soundcard to work. However, from time to tiime when problem arises (such as can not reroute sound to headphone jack), it is recommended to stop the soundcard driver and forcely remove the file before restart the soundcard driver to remedy the problem.

it records inputs behaves like virus
Important realtek driver thingie. Someone on another board deleted it and got his sound screwed up. Very common on ACER portable computers, necessary for the sound to work right.
It ran my cpu up to 100% Can't remove it, but I can rename it (RtkBtMnt.exe.bak)and kill the process; then it appears again. Renaming it and replacing with a zero byte (empty text file) stops it from reappearing and subsequently fixes my cpu overuse.
